Description of the invention (3) The fuel gas supply mechanism supplies fuel gas to the aforementioned combustion furnace And at least one of the abnormal notification. By this means, when the abnormal response mechanism stops supplying fuel gas to the combustion furnace from the fuel gas supply mechanism, the incomplete combustion of the combustion furnace can be immediately stopped, and When the aforementioned difference is known, the user is allowed to recognize that the combustion furnace has generated incomplete combustion, and urged the combustion furnace to be closed, so that the incomplete combustion of the combustion furnace can be prevented from continuing. Also, the "second aspect of the present invention" The heating cooker has: an oxidation catalyst, which is provided near the exhaust port; a temperature detection mechanism, which is used to detect the temperature near the oxidation catalyst; & a combustion abnormality corresponding mechanism, which is used in the aforementioned combustion furnace During combustion, when the detection temperature of the temperature detection mechanism is equal to or higher than the predetermined temperature, the combustion is stopped by the fuel gas supply mechanism toward the combustion. At least one of the fuel gas supply and the abnormal notification is heavy. According to the present invention, if the combustion furnace generates incomplete combustion, and unburned gas is discharged through the exhaust passage, the unburned gas introduced into the exhaust port is introduced. It will be in contact with the oxidation catalyst and air near the exhaust port to perform catalyst combustion that does not generate a combustion flame. Therefore, the combustion flame generated by the secondary combustion will not overflow from the exhaust port. In addition, the combustion due to the consumption of the catalyst The generated incomplete combustion gas can also have an effect of reducing the concentration of incomplete combustion gases such as C0 discharged from the exhaust port. Moreover, because the catalyst will generate heat as the catalyst burns, the corresponding mechanism for the abnormal combustion is When the detection temperature of the aforementioned temperature detection mechanism near the exhaust port is higher than a predetermined temperature, it is judged that catalyst combustion occurs, 538218 A7 B7 V.

Also, due to the incomplete combustion of the aforementioned combustion furnace and the secondary combustion of the gaseous gas, the temperature and concentration of the unburned gas are not limited. It is assumed that the state reaches a certain level, but because the aforementioned catalyst combustion is generated when the temperature and concentration of the unburned gas are lower than when the secondary combustion occurs, according to the present invention, the aforementioned incomplete combustion can be detected early. In the second aspect, the temperature detection mechanism detects the temperature difference between the upstream side and the downstream side of the oxidation catalyst as a method for detecting the temperature, and the catalyst combustion can be reliably detected from the temperature difference before and after the combustion of the catalyst. In a third aspect of the present invention, the heating cooker includes: a secondary air flow inlet, which is provided in the middle of the exhaust passage; and a flame detection mechanism, which is provided near the inlet and is used. Those who detect the combustion flame; and, the corresponding mechanism for the abnormal combustion is used in the combustion of the aforementioned combustion furnace, and is measured by the flame detection mechanism. The secondary combustion is generated when a combustion flame, stopping the supply of at least one of both the fuel gas and the abnormality notification from the combustion furnace toward the fuel gas supply means. According to the present invention, if the combustion furnace generates incomplete combustion and the unburned gas is discharged through the exhaust passage, the unburned gas introduced into the secondary air flow inlet provided in the middle of the exhaust passage will be connected with The air flowing in through this inlet contacts the secondary combustion. At this time, since secondary combustion occurs in the exhaust passage, it is possible to suppress the flame from overflowing from the exhaust port. And, the aforementioned combustion abnormality corresponding mechanism applies the Chinese national standard (CNS) A4 specification (210X297 mm) by setting the paper size attached to the aforementioned secondary air inlet. 538218 5. Description of the invention (near the aforementioned flame detection mechanism.),出 一-The burning flame generated by the person's combustion is withered. Since the supply of at least one of the fuel gas and the abnormal notification by the arrow gas supply mechanism to the aforementioned combustion furnace is stopped, the foregoing combustion furnace can be prevented from continuing to fail. It is completely burned. In addition, in the aforementioned third embodiment, the flame detection mechanism is provided in the path where a claw is inserted into the air from the primary air inflow port, so the air can be cooled by the secondary air. Flame detection, ^, and money structure 'Asian hunting suppresses the deterioration of the aforementioned flame detection mechanism generated by heating. In addition, according to a fourth aspect of the present invention, the heating cooker has: a secondary air flow inlet' system In the middle of the aforementioned exhaust path; oxidation catalyst: 'near human-robot, temperature detection mechanism, located near the oxidation catalyst; & combustion The constant response mechanism is used for the combustion of the aforementioned combustion furnace. When the detection temperature of the temperature detection mechanism is higher than a predetermined temperature, at least one of stopping the supply of fuel gas from the aforementioned fuel gas supply mechanism to the aforementioned combustion furnace and an abnormality notification is performed. According to the present invention, if the combustion furnace generates incomplete combustion and the unburned gas is discharged through the exhaust passage, the unburned gas or the like introduced into the secondary air flow inlet provided in the middle of the exhaust passage. The catalyst will be in contact with the air flowing in through the inlet and the oxidation catalyst, and the catalyst will be burned. Also, as in the second aspect, when the detection temperature of the combustion abnormality responding mechanism is above the predetermined temperature, It is judged that catalyst combustion occurs, and because the supply of fuel gas from the fuel gas supply mechanism to the burner and the notification of abnormality are stopped to = one, the burner can be prevented from continuing to burn incompletely. 538218 V. Description of the invention (6) The agent burns, so that the vicinity of the exhaust port can be prevented from becoming high temperature. In addition, in the description of the fourth state #, the aforementioned temperature detection mechanism detects the upstream blood of the catalyst and the blood -p, iA, and y / t. The temperature difference is used as a method to detect the temperature, and the temperature of the catalyst can be reliably detected from the temperature after the catalyst is dropped, and the temperature is reduced. ~ 'The third aspect and the fourth aspect are also detected. In the above-mentioned exhaust passage, the downstream side is provided with an exhaust passage blocking mechanism. The exhaust passage blocking mechanism is used to obstruct the ventilation of the exhaust passage, and promotes the combustion exhaust of the combustion furnace. The mixture of the air flowing in from the aforementioned secondary air inlet; #This makes τ easy to produce the aforementioned secondary combustion and the aforementioned catalytic combustion. Furthermore, the incomplete combustion of the aforementioned combustion furnace can be detected early.

The mouth 1 is followed by the description of the first embodiment of the present invention with reference to Fig. 1 (b) and Fig. 2 (a): Fig. 1 (b) and Fig. 2 (a) It is a cross-sectional view viewed from the left side of the old gas station 1. Burning furnace 2 & The pipes communicate with each other, and the fuel gas is injected from the gas nozzle 12 connected to the front end of the gas supply pipe U to the mixing pipe (U), and the combustion air sucked into the exhaust fan 5 is supplied to the mixing pipe via: 10, the fuel gas and the combustion air are mixed in the mixing pipe 10. Moreover, the mixed gas of the fuel gas and the combustion air reaches the combustion furnace 2a, and the combustion furnace 2a is burned by a complete combustion, = the combustion exhaust of the furnace 2a is from the combustion chamber] 4 through the exhaust passage! 5 and exhausted through exhaust port 4. "Here, the 'target combustion amount of the combustion furnace 2a is set by the heating amount setting switch provided on the operation panel 7', and the controller 6a determines the supply amount of the fuel gas and the combustion air according to the target combustion amount, so that To maintain the air fuel, the combustion furnace 2a is burned. 1. The controller 控制 controls the supply and exhaust by referring to the data related to the number of rotations of the supply and exhaust fan 5 and the supply of combustion air in memory. The number of rotations of the fan 5 sets the supply of the two gases for combustion. However, if dust and oil are adhered to the air supply path (not shown) and the air supply path 15 connected to the air supply space 13 by the air supply and exhaust fan 5, None: Supply of combustion air commensurate with the number of revolutions of the supply / exhaust fan 5. From this result, the supply of combustion air is inadequate with respect to the supply of fuel gas #, resulting in incomplete combustion of the combustion furnace 2a. Therefore, in order to measure the incomplete combustion of the combustion furnace 2a, a thermoelectric 538218 is provided near the exhaust port 4. V. Description of the invention (12 Full combustion, the unburned gas and the like will be sent to the exhaust port 4 through the exhaust passage 15 , And related to The secondary air inlet 3 5 enters the gate and the air rolling from the diaphragm enters the oxidation catalyst 3 7 together to generate catalyst combustion. And the heat generated by the combustion of this catalyst (see the aforementioned chemical formula (1), ⑺) The temperature in the vicinity of the oxidation catalyst 37 will increase. Therefore, as in the aforementioned & implementation mode, the controller 6 (1 when the detection temperature of the thermoelectric heater is above a predetermined temperature) judges that catalyst combustion occurs and stops supplying the combustion 2a. The fuel gas is turned on (not no) on the abnormal lamp provided on the operation panel 7. As a result, the controller 6d can prevent the combustion furnace 2a from continuing to be incompletely burned. In addition, the same as the second embodiment, the fourth embodiment The implementation type is provided with a thermocouple 39 on the upstream side of the catalysis catalyst 37. When the difference between the detection temperature of the thermocouple type and the detection temperature of the thermocouple 39 is greater than or equal to a predetermined temperature, it is judged that catalyst combustion occurs. (a) As shown in the figure, in the third embodiment described above, the effect of cooling the thermocouple 32 can be obtained by providing the w thermocouple 32 in the inflow path of the air 40 flowing from the secondary air inlet 30. ... and As a result, deterioration of the thermocouple 32 generated by heating can be suppressed. As shown in FIG. 5 (b), in the third embodiment, a blocking plate 45 (equivalent to In the exhaust passage blocking mechanism of the present invention), a vortex can be generated between the air 42 flowing in from the inlet 30 and the unburned gas etc. 43 sent out from the exhaust passage 15. This can promote the second air and the unburned gas, etc. Mixing and easy to produce secondary combustion. In addition to the aforementioned fourth embodiment, the mixing of secondary gas and unburned gas is also promoted by providing a blocking plate 45, and it is easy to generate a catalyst combustion furnace map.

Description of the invention (14 agent burning produce. In this version, only the type “*” is used. Although a thermocouple is used as the fire detection mechanism of the present invention, other types of fire, such as a fire branch (Fiame Rod), can be used. Also, although a thermocouple is used as the base, Invented temperature detection mechanism 'but also other types of temperature detection elements such as thermistors. In the Bebesch type, when the incomplete combustion of the combustion furnace 2a is detected, I will stop the supply of fuel gas to the combustion furnace 2a and notify the abnormality of the two actions. effect. In the eight-bodied type, although a two-space U population (30, 35) is provided below the exhaust passage 5, a secondary air flow inlet may also be provided on the side of the exhaust passage 15. In this κ-yoke type tragedy, although the three combustion furnaces 2a, 2b, and 2c are all represented by gas stations in the combustion chamber with the glass plate 3 as the top plate, if at least one combustion furnace is housed in the glass plate 3 After the top plate is used as a gas table in the top plate combustion chamber, it can be applied to the present invention. In this example, although the forced combustion type gas station that supplies the combustion air to the combustion chamber by the exhaust fan is shown, the natural combustion type gas station that does not include the exhaust fan can also be applied to the present invention. . In addition, as described above, in the forced combustion type gas station, the amount of fuel gas and combustion air supplied to the combustion furnace is adjusted, and the combustion amount of the combustion furnace is changed to control the heating amount of the heating material.
